' COMPOSITE BUILDING-BEAM.

Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed May 14, 1912. Serial No. 697,291.

To all whom t may concern Be it known that I, WILLIAM PrNoKNEY FRANCIS, a citizen of the United States, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved Composite Building- Beam, of which the following is a full, clear, and exact description.

The present invention relates to improvements in an improved composite beam structure, for which Letters Patent of the United States were granted to me under date of May 3, 1910, bearing No. 957 ,048.

Among the objects of the present invention are the following: To provide an economical and simplified construction; and to provide anchoring devices for uniting the masonry and the metal structure, the arrangement of which distributes uniformly the breaking of the strain over the entire structure.

Reference is to be had to the accompanying drawings forming a part of this specification, iny which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a perspective view of a building beam constructed and arranged in accordance with the present invention, the beam being shown in conjunction with supporting structural piers therefor; Fig. 2 is a detail View, on an enlarged scale, showing in section a fragment of said beam in the course of construction; and Fig. 3 is a cross Sectio-n of the complete beam, the section being taken on the line 3 3 in Fig. 2. l

As seen in the accompanying drawings, the masonry of the beam is primarily supported upon framing members consisting of two angle irons 8. The angle irons 8 are spaced apart, the flanges thereof being disposed in parallel relation, and perfo-rated to receive tie-bolts 9. The tie-bolts 9 are provided for engagement of the hook endsV Y as shown in the accompanying drawings,

consists of tiles 14, registers with the top course of each of the piers 13, to give the semblance of a continuous and harmonious masonry structure. The tiles 14 are supported by metal straps 15, bent and overlaid upon the horizontal flange of the angle-irons 8, as more fully set forth in the patent above referred to. Whenthe tiles are fully set, the first course of the masonry work, or of the bricks 16, if such me employed, is laid upon the top of said tiles and the horizontal anges of the angle irons 8. Succeeding courses of brick: are then laid, which, as soon as the brick course rises above the edge of the vertical fianges of the angle irons, is carried over said flanges. As this is carried into effect, the tie-rods 11 are adjusted to the proper inclination, substantially as shown in Fig. 2 of the drawings. The disposition of the rods 11 is such as to convert or transfer the load from any particular part of the beam structure toward the ends of said struct-ure resting upon the supporting piers 13. This is accomplished by the arrangement of the rods in the manner shown. After the rods are set at the desired angle, the construction of the masonry of the beam continues until the interspaces between the rods have been completely filled by the masonry, wh-en, it will be found, the rods are rigidly held within the masonry construction, and the anchor hooks 12 are firmly engaged in the masonry, to resist any pull upon said rods.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A composite beam, comprising a plurality of metal angle irons, the vertically-disposed flanges whereof are united by tie-bolts to form a metal T-beam having a standing web and horizontal flanges; a facing for said beam, embodying a plurality of tiles structurally united with, and supported upon, said T-beam; a composite masonry Structure built upon said T-beam and the facing tile thereof; and a plurality of tie-rods engaged with said bolts and disposed within said masonry at an angle inclined from the horizontal.

2. A composite beam, comprising a plurality of metal angle irons, the verticallydisposed fianges whereof are united by tiebolts, to form a metal T-beam having a standing web and horizontal flanges; a facing for said beam, embodying a plurality of tiles structurally united with, and supported upon, said T-beam; a composite masonry structure built upon said T-beam and the facing tile thereof; and a plurality of tierods engaged with said bolts and disposed within said masonry at an angle inclined from the horizontal, said rods being provided with horizontally extending anchorhooks to overlie said masonry, to be supported thereby.

` 3. A composite beam, comprising a plurality of metallic angle-beams spaced apart; tie-bolts extended between the adjacent flanges of said beams; a facing for said beams, embodying a plurality of tiles having incorporated in the structure thereof metal straps adapted to overlie said angle beams to support the facing tiles; a superposed masonry built upon said angle-beams and said facing tile; and a plurality of elongated tie-rods embedded in said masonry and engaging said tie-bolts, said rods being equally disposed at opposite sides of the center of said beam, and having elongated anchor hooks to overlie and engage the masonry built on said angle beams, to distribute the load thereon, said tie-rods being each inclined toward its adjacent beam-supporting pier.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
